A subcontractor who consistently turned down construction work would also be deprioritized by a general contractor.

Because Uber, Lyft, and others periodically offer different incentives in the market, I could make a case that by deciding to sign up on a specific day or respond to a specific offer, you had a chance to accept or decline the company's offer. There's nothing stopping you from reaching out to Uber or Lyft corporate and trying to negotiate your rate. I predict you won't succeed, anymore than the drywall contractor example upthread.
